              --------
accept such assignment, effective for all purposes as of December 15, 2000 (the
"Exchange Date"), of PM's rights under the KFNA Notes, including without
limitation PM's right to receive principal and interest payments thereunder;
provided that all interest accruing under the KFNA Notes up to but not including
--------

<PAGE>

                  (b)      LLC agrees to issue the LLC Notes to PM effective as

         2.       Consent and Acknowledgment of KFNA.  KFNA hereby consents
                  ----------------------------------
to the assignment of the KFNA Notes by PM to LLC and acknowledges LLC's rights
under the KFNA Notes as the assignee of PM.

         3.       Mandatory Prepayment of Kraft Notes.
                  -----------------------------------

                  (a)     The parties agree that until the KFNA Notes have
been repaid in full, an amount equal to the net proceeds of any external
financings of any kind conducted by KFNA or Kraft Foods Inc., whether through
the issuance of debt or equity (the "Prepayment Amount"), shall be payable by
KFNA to LLC or its assignees as a mandatory prepayment of principal of the KFNA
Notes in the priority set forth in Section 3(b) immediately upon receipt of such
Prepayment Amount by KFNA or Kraft Foods Inc. Notwithstanding the foregoing, no
prepayment of the KFNA Notes shall be required in respect of (i) any short-term
debt, (ii) any compensation-related equity issuance, (iii) the portion of the
net proceeds of any external long-term debt financings issued after the date
hereof ("New Debt") up to an amount equal to the portion of the aggregate
principal amount of external long-term debt of Kraft Foods Inc. and its
consolidated subsidiaries outstanding on the date hereof ("Existing Debt")
having scheduled maturities within the same calendar year as such New Debt
issuance, or (iv) New Debt issued within the same calendar year as maturing New
Debt up to the amount such maturing New Debt was used to refinance Existing Debt
pursuant to clause (iii) above. In the event multi-tranche New Debt is issued
and only a portion of the proceeds thereof is used to refinance maturing
Existing Debt pursuant to clause (iii) above or New Debt pursuant to clause (iv)
above, such portion shall be deemed to have matured first, on the earliest
maturity date of such refinancing and thereafter, any balance remaining shall be
deemed to have matured on the next earliest maturity date of such refinancing
until such portion is fully allocated.

                  (b)     In the event of a mandatory prepayment pursuant to
Section 3(a), the Prepayment Amount shall be applied toward the prepayment of
the KFNA Notes in the following order of priority:

                  first, to the prepayment of the KFNA $11 Billion Note;


                  second, if the KFNA $11 Billion Note has been paid in full,
                  the balance shall be applied to the prepayment of the KFNA $4
                  Billion Note; and


                  third, if the KFNA $4 Billion Note has been paid in full, the
                  balance shall be applied to the prepayment of the KFNA $5
                  Billion Note.


                  (c)     The unpaid principal balance of the KFNA Notes,
together with any accrued but unpaid interest on the KFNA Notes, shall become
immediately due and payable, without presentment, demand or other formalities of
any kind, all of which are hereby expressly waived by KFNA, on the date on which
PM ceases to control the vote, directly or indirectly, of shares representing
more than 50% of the aggregate voting power of all the voting stock of KFNA.

         4.       Mandatory Prepayment of LLC Notes.
                  ---------------------------------

                  (a)     LLC and PM agree that until the LLC Notes have been
prepaid in full, an amount equal to the Prepayment Amount received by LLC from
KFNA pursuant to Section 3(a) shall be payable by LLC to PM as a mandatory
prepayment of principal of the LLC Notes in the priority set forth in Section
4(b) immediately upon receipt of such payment by LLC.

                  (b)     In the event of a mandatory prepayment pursuant to
Section 4(a), such prepayment shall be applied toward the prepayment of the LLC
Notes in the following order of priority:


              first, to the prepayment of the LLC $11 Billion Note;


              second, if the LLC $11 Billion Note has been paid in full, the
              balance shall be applied to the prepayment of the LLC $4 Billion
              Note; and


              third, if the LLC $4 Billion Note has been paid in full, the
              balance shall be applied to the prepayment of the LLC $5 Billion
              Note.


                  (c)     The unpaid principal balance of the LLC Notes,
together with any accrued but unpaid interest on the LLC Notes, shall become
immediately due and payable, without presentment, demand or other formalities of
any kind, all of which are hereby expressly waived by LLC, on the date on which
PM ceases to control the vote, directly or indirectly, of shares representing
more than 50% of the aggregate voting power of all the voting stock of Kraft
Foods Inc.


         5.       Conflicts.  The Kraft Notes and the LLC Notes are governed by
                  ---------
the provisions of this Agreement. In the event of a conflict, the provisions of
this Agreement shall prevail.


         6.       Governing Law. The substantive laws of the Commonwealth of
